Review on rail corrugation studies

Wear, 2002
In Japan, rail corrugations had not been so serious formerly, but it began to be prevailing in recent years. In order to prevent the generation of rail corrugation, many studies have been reported in the world since the end of 19th century, but theories on them have not explained the formation mechanism perfectly and no perfect countermeasures have ...

Systematical Analysis of Rail Corrugation in Urban Rail Transit

Journal of Convergence Information Technology, 2013
Abstract Rail corrugation is an adulatory wear which is similar to wave in shapes that can be observed on the rail rolling surface along the longitudinal direction after the rail is put into use. In this paper, a vehicle-track coupled finite element model is established to analyze the reason of rail corrugation systematically in urban rail transit. The

Experimental study on mechanism of rail corrugation using corrugation simulator

Wear, 2002
This paper presents experimental study on corrugation phenomenon growing on the top surface of rail in a tight curve of track. One of the characteristics of the corrugation is to involve a slight slip, i.e. creepage, in rolling contact surfaces between rails and wheels.

Study on Rail Corrugation Development Mechanisms

2021
On railway tracks, the corrugation that frequently occurs on the inner rails of sharp curves often results in noise and vibration. However, since there are no widely accepted theories on the evolution of such corrugation, nor countermeasures to prevent it, it is necessary to clarify the mechanisms governing rail corrugation development.

Corrugated Waist Rail Microstructure Evolution Simulation

Advanced Materials Research, 2014
Applying the research result of the whole corrugated web H-beam to rail structure, a new kind of rail structure, the corrugated web rail was generated. The special structure rail was successfully rolled in the Research Mill Institute of Yanshan University.

Considerations on Rail Corrugation

Vehicle System Dynamics, 1994
SUMMARY The paper consists of three parts 1.Description of a One-Dimensional Corrugated Surface The surface is modelled as a periodic, differentiable function of the distance traversed. Three criteria of corrugation growth are developed 2. The Frequency Response of Wheel and Rail A linear relationship is assumed between the Fourier transforms of the ...

Rail Corrugation: Characteristics, Causes and Treatments

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 1993
Corrugation is a phenomenon which has excited the interest of railwaymen for more than a century, but for which there often does not appear to be a cure. It has generally been realized that there are in fact different corrugation mechanisms, and that some types of corrugation can indeed be prevented.

Surface analysis of corrugated rail treads

Wear, 1990
Abstract Corrugated rail treads were examined by surface analysis. The results led to the conclusion that the vibration of the wheel-tread system leads to different amounts of load at different areas of the surface. As a consequence there are areas with higher loads, higher deformation, higher hardening and higher wear resistance: the “hills ...

An experimental study of rail corrugation

Wear, 2003
Abstract This paper presents experimental study of rail corrugation using a JD-1 wheel/rail simulate facility, which mainly consists of a big wheel serving as the rail, and a small wheel serving as the locomotive or rolling stock wheel. The power delivered to each testing wheel can be accurately controlled.

Analysis of rail corrugation in cornering

Wear, 2008
Rail corrugation in cornering is examined via a non-linear time-domain model of a bogie cornering. The model is computationally fast due to a modal description of a wheelset that includes bending and twisting modes of its axle as well as flexing of wheel hubs.
